b. wherein the two solar modules (1) of the at least one double module arrangement are coupled together only in the region of their mutually facing upper edges (2).

Description

The The invention relates to an arrangement of solar modules on surfaces, in particular roofs, according to the preamble of the claim 1.

Generic module arrangements are from the DE 100 47 400 C2 as well as from the DE 20 2008 007 549 U1 known. These documents each disclose solar module arrangements, which are arranged by means of mounting devices in a so-called folding arrangement on a roof, such that they form a zigzag arrangement in a side view. This type of zigzag arrangement makes it possible to completely or almost completely cover a roof surface with solar modules, which optimizes energy production, in particular when the folding or zigzag arrangement is oriented in an east-west direction.

adversely in the two constructions mentioned and more generally in the The state of the art is the high use of materials with regard to the mounting devices or substructure. In particular, the known mounting devices Relatively many components and components.

In front This background is based on the generic Prior art, the object of the invention, the generic Arrangement in terms of their substructure as well as in respect to simplify the mounting device.

The Invention solves this problem by the subject matter of the claim 1.

advantageous Embodiments of the invention are the subclaims refer to.

The The invention provides a module assembly comprising: at least one or more double module assemblies of two angular aligned solar modules; the two solar modules the at least one double module arrangement only in the area of their mutually facing edges are coupled together. hereby no expensive supporting profiles required according to the state of the art in particular the lower support profiles or cross members or also called basic strivings. This results in cost savings and a simplified assembly.

Of the Concept of solar modules includes solar elements of various kinds, which form a kind of preassembled module and those for the production of energy in the form of electricity and heat. The inventive Type of mounting arrangement) is therefore suitable for both photovoltaic modules as well as for thermic collectors and may preferably arranged on flat roofs or pitched roofs be, but also on any open spaces. Other advantages are the aerodynamic arrangement of the solar modules, resulting in Weighting or anchoring unnecessary.

It is particularly advantageous and easy if the two solar panels each double module arrangement only via one or more Connector especially in the area of its "upper" edge coupled together and when the facing away from each other "lower" edges each double module arrangement not with each other via a profile are connected.

About that In addition, however, it is supplementary to a particularly advantageous Variant of the invention provided that adjacent to each other Doppelmodulanordnungen - in interaction then form a kind of zigzag arrangement - about Coupling devices are interconnected.

To a particularly preferred variant of the invention form these Coupling devices turn off anti-slip devices, d. h., they counteract a sliding on a surface. she are preferably supported without a fastener an underground and are preferably designed such that they have a relatively high static friction to the ground. Act adversely Weights are therefore usually not required.

It is also functional and constructive especially easy if the anti-skid devices over at least another connector with one or more dual module arrangements are coupled.

It is also particularly advantageous when the anti-skid devices also the function of a load transfer of the double module arrangements take over in the underground.

Especially Preferably, the anti-skid devices are configured in such a way that that the distance between the lower edges of adjacent double module arrangements 50 to 500 mm, preferably 300 mm, which is the maintenance again simplified.

Preferably the anti-skid devices are further configured in such a way that the gap between mutually adjacent Doppelmodulanordnungen is walkable.

According to a further preferred variant, at least one profile is arranged under the solar module, in particular under glass-glass thin-film laminate modules, which has one or more chambers, which for receiving the verbin which is / are designed.

following Again, some advantages of the invention are listed.

Created is a mounting arrangement, in a preferred design without additional Ballast and or attachment to the ground gets by.

The Mounting arrangement is particularly suitable for unframed Solar elements (laminates, preferably thin-film laminates made of double safety glass).

A separate substructure, which is attached to the building, is not required because the module supports and supports yourself. Also on wind deflectors can be dispensed with.

It becomes an arrangement with a very high area ratio created by solar elements, which are controlled by a unobstructed water drainage, good accessibility in the inspection aisles and a simple and safe cable laying distinguished in the revision courses.

Especially advantageous as a development of the subject matter of claim 1, but to consider as a separate invention is the used Anti-skid device for maintaining row spacing, which serves as a pressure element and also for receiving horizontal Shear forces, z. B. by wind, as well as the connection at least two, lower solar element edges.

The Anti-skid is preferably as a support plate for load transfer educated.

The Connecting angles are preferably made of stainless steel and are clamped in profile grooves in profile grooves preferably a profile of solar modules in training as laminates with a profile that is called a backrail (frameless elements).

following the invention is based on an embodiment below Referring to the drawing explained in more detail. It shows:

1 a perspective view of an assembly formed from a mounting arrangement of solar modules on a flat roof;

2 a side view of a series of solar modules;

3 and 4 in each case a side view of a multi-row solar module arrangement and a plan view of this solar module arrangement;

5 a sectional view of a profile;

6 a sectional view of a connector;

7 a sectional view of another connector;

8A B is a side view and a perspective view of an anti-skid device; and

9 a perspective view of another anti-skid device.

1 shows a module assembly according to the invention, the at least two - as in 2 - or a variety of solar modules 1 having.

To simplify the discussion 2 and 3 provided with a Cartesian coordinate system. In this case, the coordinates X and Y respectively describe the coordinates of the surface or installation surface assumed here for the solar modules and the supplementary coordinate Z the coordinate perpendicular thereto. In the case of a flat roof or other flat ground, the X and Y coordinates correspondingly indicate that area, whereas the Z coordinate is the vertical coordinate, respectively. From this orientation, the following terms such as "top" or "bottom", which are not to be understood as limiting, especially as the invention for obliquely oriented surfaces such. B. is suitable for a pitched roof.

noted Let it be true that the following is consistently the concept of Solar module is used, but this is representative of Modules of various types such as solar cell modules or thermo modules to understand.

The solar modules 1 of the 1 preferably have a relatively flat, rectangular basic shape. Two each of the solar modules 1 are by means of connectors 6 . 7 that exemplifies in 6 and 7 are mapped to each other in such a way that in each case two of the solar modules in pairs in the region of one of its outer edges 3 lie against each other and thereby enclose an angle α, which is preferably - but not mandatory - greater than 90 °.

Preferably, a plurality of such double module arrangements in a row (direction X) are arranged one behind the other. In addition, it is possible to arrange a plurality of these rows of double modules next to each other (direction Y) on a substrate such as a roof, to a roof surface or the like as desired - in particular also over the entire surface - to cover with solar modules.

Out this type of arrangement results in the name zigzag arrangement or folding arrangement.

Across from The prior art, the substructure is significant has been simplified.

The double module arrangements are in the mounting arrangement according to the invention in each case at the mutually facing, in the erecting position vertically upper edges 2 connected to each other, but not in the area of facing away from lower edges 3 ,

Instead In the mounted position, it connects to the ground self-realized. An underground connection in the area of the opposite lower edges is within a double module arrangement but not available or is saved.

Compared to the state of the art, as he from the DE 20 2008 007 549 U1 is known, so that a double module arrangement is created with a significantly simplified structure, because it can be dispensed with there existing intermediate carrier or profiles, which interconnect the lower opposite edges of each double profile arrangement. Preferably also in the area between the connectors 6 . 7 and the lower edges 3 no additional support strut available.

Adjacent, adjacent double module arrangements also become in the region of the adjoining (here lower) edges 3 connected via coupling devices or elements. These coupling elements preferably realize such a spaced connection of the lower edges 3 adjacent double module arrangements that for assembly purposes or maintenance good accessibility to the dual module arrangements is ensured.

Preferably, the distance between the lower edges 3 the adjacent double module assemblies 50 to 500 mm, preferably 300 mm. The distance between the lower edges 3 is preferably predetermined by one or more coupling devices.

It is beneficial and acts to stabilize the construction if the anti-skid device roughened on one side is or provided with a friction-enhancing coating is.

following be preferred embodiments of these coupling elements closer considered.

In a particularly preferred embodiment, the coupling elements or devices form one-piece or multi-piece anti-slip devices 4 (see in particular 8th to 9 ) out.

The anti-slip devices 4 are preferably not only designed to realize a non-slip for the double module arrangements but also take over the function of load transfer into the ground.

At each anti-slip device 4 are preferably at least two edges 3 two adjacent double module arrangements arranged or fixed, preferably four of the edges 3 , so that four of these solar modules can be mounted or mounted according to the anti-slip device.

2 shows a series of double module assemblies in a side view, wherein the solar modules 1 how to 1 described, are set up at an angle to each other. Here are the upper edges 2 kept at a small distance. Under the solar elements 1 (here a glass-glass thin-film laminate) are profiles 5 preferably aluminum profiles, which preferably have chambers which serve to receive the connector or other fastening means.

At the upper edges 2 is a connector 6 in the recesses of two adjacent solar modules 1 introduced.

The connector 6 is - see 6 - Preferably designed as a one-piece elbow and has two legs 12 . 13 on, which include the angle α.

In the preferred case, this angle α is 160 °. This shows the solar elements 1 an oblique inclination or orientation of 10 degrees to a flat - for example, horizontally oriented - underground.

The lower edges 3 adjacent double module assemblies are also directed to each other in a larger collector array. For mounting is also in the profile 5 at the lower ends a connector 7 used. Such is the connector 7 on the profile 5 and thus fixed to the solar module. It is conceivable the profile 5 and the connector 7 screw together. On the edge 3 or the profile 5 opposite side is the connector 7 in contrast, with one of the anti-slip devices 4 connected.

This anti-skid device of 8th is a particularly preferred embodiment. In addition, however, embodiments of the invention conceivable in which the lower edges 3 the solar elements 1 be connected directly to each other.

The preferably used anti-skid devices 4 absorb pressure forces that are applied by the individual module rows through the 10-degree arrangement. Overall, the pressure forces cancel.

The slip locks 4 are preferably with protruding pins 8th provided, preferably grub screws, on which the connectors 7 with appropriate holes for easy mounting easily put on. It is then only necessary, the connector 7 with a nut on the slide locks on the grub screws 8th tighten.

The slip locks 4 In addition, preferably form a so-called revision gear between adjacent double module arrangements, which the maintenance - as already mentioned - the module assembly significantly simplified.

2 illustrates that no further profile mounting support system, no further transverse strut within the dual module assemblies, no support struts or the like are required as described in the prior art.

The zig-zag arrangement is particularly preferred only by the anti-slip device 4 between adjacent dual module assemblies, a connector 7 between the geiticherseinrichtung 4 and the dual module assembly, a profile 5 , on which the solar module is arranged, a connector 6 between the upper edges or profiles 5 adjacent solar modules formed a double module assembly. This can turn connectors 7 , Anti-skid devices 4 etc. connect.

At the ends of larger module fields can absorb the compressive forces between the profiles 5 or between the connectors 7 a tension element can be arranged. This tension element (not shown here) may be a pull rope or a pull rod. As a result, the entire module field is free to install without an attachment in the ground or without weights. The aerodynamic arrangement also prevents wind forces from reaching under surfaces, so that lifting is not possible.

The 3 and 4 symbolically show again a module field that can be expanded and enlarged as desired. 3 shows the important for this application order of attachment, consisting of anti-skid, connector, profile with solar module, connector, profile with solar module, connector, anti-skid device, etc.

Below The solar elements are not connecting or supporting Components. Drainage is easily possible, as well as the access to the modules.

5 shows in a sectional view enlarged the profile 5 , the surfaces 9 on which the solar modules 1 (not shown here) may rest and may be glued.

The profile 5 also has an open hollow chamber 10 on, in which the connector or other mounting elements can be arranged.

This profile 5 is a particularly advantageous option as a holding element for the solar modules. Alternatively, it is conceivable to fix the connectors directly to a module frame - if present - or to another part of the module or to couple with it, so on special mounting holes or the like ..

6 shows in section a connector 6 , the two solar modules of a double module arrangement in the region of the mutually facing upper edges 2 connects with each other.

The connector 6 has at least the two thighs 11 and 12 on, which are aligned at an angle to each other. Preferably is that of thighs 12 . 13 included angle α between 100 ° and 175 °, preferably at 160 °.

In addition, the connector has 6 on the thighs 12 . 13 preferably through holes z. B. threaded holes on, for easy clamping of the connector 6 by means of screws in the profile 5 are provided.

7 shows a double-curved connector 7 , which determines the lower edges 3 the solar elements 1 is designed. The connector 7 has a support leg 7a on, a vertically aligned vertical leg here 7b , and one here at an angle β of 90 ° + (180 ° - α) / 2 = 180 ° - α / 2 aligned further skew leg 7c for fixing to the solar modules. The connector 7 preferably also further has bores for connection to the profile 5 or with the anti-slip device 4 are designed.

The 8A and B shows an anti-skid device 4 which is essentially used as a connecting element between the lower edges 3 the mutually facing edges 3 serves adjacent double module arrangements.

The distance of the connection is chosen to be relatively large at 300 mm and thereby gives the advantage that between the double module arrangements Revision is formed. This revision gear is not absolutely necessary, but also serves advantageously for laying the power cable.

8A shows a first anti-slip device in a side view, the anti-skid device here from a lower plate 15 exists on the at least one push rod 16 is arranged. On the push rod 16 , which could also be referred to as a spacer bar, are pins 17 , preferably threaded pins, for connecting the anti-skid device to the connector 7 for the lower edges 3 the solar elements 1 ,

9 also shows an anti-skid device 4 ' , which is designed for cost reasons without pressure rods. To the sheet metal 15 ' to give additional stability, in particular pressure stability, is the sheet 15 ' canted on the sides. Additional beads or sheet metal stiffeners are another advantageous addition.

Next to the pins 17 has the anti-skid device 4 ' in the lateral edgings oblong holes 18 on, which serve for the attachment of cable clamps and the like.

Basically, the anti-skid device 4 at its bottom 19 Thus, on its side facing the roof, have a special configuration, preferably a roughening or a friction-increasing coating.

These Can be used as an adhesive surface or a rubberized surface be formed or with stripes such. B. EPDM strips provided be or be designed in any other way such that slipping the elements on the ground is prevented.

The background to this is the fact that wind forces acting on the module field, have only a relatively small lifting effect but a relatively large sliding effect, ie lower forces in the vertical direction and greater forces in the horizontal direction. The anti-skid devices are therefore also suitable without additional weighting and without attachment to the roof or subsoil surface to absorb corresponding wind loads. The footprint is also so large (preferably it is more than 200 mm x 200 mm, in particular more than 400 mm x 300 mm, so that the weight forces are well distributed.) Preferably, the anti-skid devices are located 4 then only on a substrate and are not fixed there with fasteners. This type of module assembly is very inexpensive, easy to assemble and yet very safe.
